Work = Force x Distance
Friction is a force usually operating in the opposite direction to the force being applied. Thus friction adds to the size of the force applied and work is increased.
Friction will work against force
Yes because work=friction ×distance
Friction's direction is always against the direction work is being applied to.
yes. to have friction you need more movement between what ever is making the friction which then brings you more work
cars work well with friction because if there was no friction and a car tried to turn it would probably slip and slide and therefore a car works pretty well with friction
friction increases the amount of force necessary to do work
In ideal case not but in real life by forces like friction, etc.

magnetism
No, We cannot do work on friction less surface
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
Yes because work=friction ×distance

No, however mass and or density is directly related to the amount of friction
yes. to have friction you need more movement between what ever is making the friction which then brings you more work
